เกจวัดแรงดันน้ำ4หุน pumping station powered by Delta CP2000 frequency drives is delivering efficient irrigation to a dairy farm in South Africa in an space experiencing irregular and ever lowering rainfall.
Five low-energy Delta CP2000 frequency drives drive the six underground nicely pumps and be positive that the water delivered to the floor is transferred on to the upper tank.
The dairy farm wanted a pump system to entry ground water from wells and guarantee a dependable and cost-effective water supply. The farm’s owner commissioned an acceptable system from electrical set up planners, Pienaar Elektries, which specialises in agricultural operations. Following an in-depth planning and session course of, Pienaar Elektries opted for a quantity of automation products from Delta.
The deliberate irrigation system comprised two reservoirs at different heights, to be full of water by a complete of six underground well pumps overnight, when the power costs had been low. A transport pump is used to transfer water from the lower reservoir to the higher one. The height distinction permits the sprinkler system to be operated utilizing gravity alone through the day, making it significantly environment friendly. The cattle and the dairy also can take their water supply from this irrigation system. The key requirements of the project have been value effectivity and low vitality consumption.
Five low-energy Delta CP2000 frequency drives drive the six underground well pumps and ensure that the water dropped at the floor is transferred on to the upper tank. The CP fashions function a PID controller with feedback that permits the water level within the tanks and boreholes to be monitored and corrected. This is done by alternating between the completely different pumps and regularly monitoring the move. If the borehole level falls under a minimum predetermined by the consumer, the PLC management switches to the following the borehole and prevents the pumps from being damaged.
The system has various Delta DVP sequence programmable logic controllers (PLCs). Three DVP04AD PLCs monitor the sensors in boreholes and maintain the water stage above the predetermined value. Five DVP16SP PLCs regulate the motors. One DVP12SE PLC displays the water degree within the prime reservoir and the animal watering stations, whereas an extra DVP controller manages the sprinkler set up. Two human-machine interfaces (HMI) from the DOP-100 series are used to display all of the processes within the system and show system information and warning indicators on a 7 or 15-in contact screen. In-house software also permits the time configuration and energy costs to be monitored remotely. Users can even monitor the entire process through the DOP-100 VNC server.
The system is now working without any issues and provides each livestock and crops with adequate water, even in periods of low rainfall.
